(F2) south of AVON - (west of Tilsonburg) Roof removed from bungalow, damage path 4km long. Info: 'The tornado warning issued Thursday for southwestern Ontario became more than a warning for a surprised Tillsonburg man. Richard Smith, 29, spotted the tornado in the early afternoon while driving along rural Avon Drive in the vicinity of Belmont. Smith saw the dark funnel cloud only moments after the tornado ripped through a nearby house. "It took out the house pretty much completely," Smith said. "There were full-grown trees being ripped right out of the ground." Describing the tornado as having almost a "lightning-bolt" shape, Smith recounted "white clouds" near the funnel's base that were "throwing up all kinds of stuff." Driving by the flattened home, Smith saw an uninjured elderly woman standing outside the wreck. There was also a report of a barn being destroyed just north of the home -- about 15 kilometres west of Tillsonburg along Prouse Road -- but, again, no one was injured. This tornado wasn't the only twister to touch down in the region. Another funnel cloud ripped the roof from an Elgin County home while a startled woman was washing her hair in the bathroom.'

Usually this list is updated with every EC update. It's been over a month and it hasn't changed with all the new info.

Actually I got a new update (4 more tornadoes added) about a week ago. I'm just waiting to update the list here. No use updating it 10X for 10 updates. I'll wait until EC is done with it, then update it.

I glanced at the list here for a quick refresher on total tornado numbers for last year and thought the count was a little off.

According to this EC summary, there were 29 tornadoes in Ontario last year, but this list only has 28 tornadoes. We have a missing mystery tornado to locate

EDIT: After scavenging through EC severe weather summaries, looks like they confirm the 27th tornado of the season in a SWS then jump to the 29th tornado. There is no statement or summary for the 28th tornado.

I want to say that tornado was in the Woodstock area but I can't remember for sure. I remember reading about it in one of the Environment Canada releases about the Aug 20th outbreak but it was only a short paragraph embeded in a big release. I believe it was a F0 tornado they conformed a month or two after it happend. I'll see if I can find anything about it anywhere.

I've been reading through 2009 severe weather summaries for two days now, but I can't find any Woodstock/Oxford County mention. Though, for some reason I feel like there was a Woodstock area tornado.
